I grew up in Manhattan, KS and attended Kansas State University to play volleyball during my undergraduate years. I then attended the University of Kansas for medical school, first in Kansas City for the basic sciences and then on to Wichita for my clinical rotations. I then headed out to Phoenix, AZ for my internal medicine residency training at the Mayo Clinic in Arizona, staying on for a fourth year as Chief Resident. During our time in Arizona, our family grew with the addition of my two children, and for this reason, we wanted to be closer to our families in Kansas for fellowship training. This search lead me back to the Heartland and ultimately after my interview at the University of Oklahoma, I knew it was the right fit for us! Our program offers a unique clinical training experience in that you care for patients across the spectrum, consisting of our Veterans, adult University hospital and Children's hospital populations. A bonus is that these 3 hospitals are all on the same walk-able campus! Our attendings are passionate about teaching, collegial and are leaders in their field. As fellows, we have adequate time to study and conduct research and still maintain a life outside of work. We have enjoyed exploring OKC and in our free time, you will find us at one of the local eateries, at a music festival, an OKC Thunder game, the Science Museum or OKC Zoo.  I know our program leadership and support staff truly care about the quality of our education and training and want us to be the best gastroenterologists we can be. I have made lasting friendships at this program and would choose OU all over again. I hope you will consider our program in your search for the right fellowship for you!

I am looking forward to starting my third year of fellowship training at OU. Oklahoma City has been a home away from home me and my family!  It was important that we go somewhere that would offer a great educational experience for my training, but also be amenable to our growing family.  Growing up in Kansas City, Kansas, the Midwest is my favorite region in the country.  I attended medical school in Kansas City, Missouri with most of my clinical rotations in Jefferson City, Missouri before completing residency at the University of Kansas in Kansas City and stayed on for a fourth year as a Chief Resident.  When looking for GI fellowship, I primarily interviewed in the Midwest and South.  Since we moved here, my husband and two young boys have kept busy on the weekend with activities in the city.  We have especially enjoyed the OKC Zoo, Myriad botanical gardens, the multitudes of food trucks and various art festivals.  There is always something to do!

One of the most striking things about our fellowship program besides the quality of the faculty is that the campus has a central location.  Everything is connected by skywalks and when you are covering call for the weekend there isn’t any extra time spent in the car.  I hope that you consider OU for fellowship as it has been an excellent experience!
